I’ve said this before but you my friend are worth every penny.
Thanks!
Do you think this motor was worth £2600?
@@BritannicaRestorations sometime ago you melted a lot of aluminium, may I suggest you fire it up again there is some melting to be done starting with that head 😂
I have 5 x 45 gallon drums full of stuff like this outside - been saving it for winter!
Haha Tizer. Can't remember the last time I had a Tizer. That's crazy, I didn't expect to see it cracked in there. Every day is a school day. 👍🏻
You and me both!
Very effective and perfectly visual experiment. Good one.
Thank you! Cheers!
Bloody hell, that was spectacular!
You’ve got a good HEAD on your shoulders mate. 👷🏼♂️ Great work. 👍🏻🦘🦘
Thanks 👍
The year starts with a leak - thanks Mike, keep them coming.
As the Cavan man said "does she burn oil...? She would if she got it"
Haha
That cavan man would be the same fella that'd peel an orange in his pocket in fear someone would ask him for a slice lol
@@TheHawkeye1313 Wearing a Boxing Glove too if he were a Yorkie.
Mike that was absolutely spot on, a very visual demonstration. I love it when a plan comes together. The engine would have white smoked a lot with that head on it, is it white smoke for I surrender!
I cannot figure out how this was sold as a re-manufactured engine
You can smell the burnt coolant too.
Sensational YT content Mr. Jameson ! Can we see a test of the block too ? V.
Possible
"You're a wizard, Harry" That was so much fun to watch. Thanks Mike!
Glad you enjoyed it!
Fantastic experiment, Mike !!!
Many thanks!
Bloody hell that’s a first I’ve never seen that before 👍👍👍👍thanks for showing us
No problem 👍
thas interesting !!! you're the best buddy. 👍🏻 learned a lot from your channel and it helped me with my work so much(LandyCareOverland). never missed an episode. From the middle east, I thank you on behalf of all of your fans and followers and also my customers. best regards FAISAL :)
Thank you for you kind words Faisal!
That should be show'n on all land rover sites.
Brilliant.
Answer this though you said not to port these heads.ashcrofts port these heads are you saying keep well away.am only asking because i was thinking of purchasing one.might think twice.
Cant wait for next vid.👍
I saw an Ashcroft high performance head once and I think all they did was tune the valves and maybe cut a few sharp points off the inside but when I looked down the ports there was still the sand casting marks - I could not tell any difference in power
@@BritannicaRestorations thanks for that mike.yes they do the work behind the valves.app.
You made my mind up now.
Many thanks.your a special sort of bloke.
@@BritannicaRestorations You would think that inlet porting would be fairly illogical anyway with a turbocharged engine compared to just turning up the boost pressure slightly. Also on the exhaust side, any trick manifold ideas for scavenging would surely be nullified by back-pressure before the turbine. My 1978 carburettor Range Rover however (sadly festering in a shed) bought with a retrofit sculptured stainless manifold, dispelled all previous misunderstandings I had that sports exhausts are waste of time!
If that head was a boat, it would have sunk before leaving the dock. Funny how a good mechanic can spot a turd without much looking. Thanks for the video.
Thanks!
Brilliant, thanks Mike.
Glad you enjoyed it
I had 2 heads (better than one) sent to Turners and they said one had a crack, but it wasn't significant because it wasn't leaking. They had a perfect chance to sell me a new one but they did the right thing. Those folks are top notch!
Name an shame Mike, they wont improve their service until it hits them in the pocket!
Working on it
A great hardworking Old School mechanic... Love it! 😀
It sure is!
Well diagnosed Sherlock2
Tizer (on the rocks?) well deserved!
Cheers Len!
Thoroughly enjoyed that Mike. All the very best for 2021. Mat
Thanks Matt!
Stunning demo!
Many thanks!
Hi Mike 🤔 just saying thanks again. 👍👍👍🇬🇧🇬🇧🇬🇧
No problem 👍
Absolute cracking video! Right up there with your best videos Mike. Keep them coming.
Thanks, will do!
MIKE!!!!! You are the master of the hidden mysteries of nature and science. I bow to you on the alter of knowledge. After 60 years plus in the game I have never seen anything like this. Such a perfect demonstration. Best wishes, Yorkshire Rob.
Aye Rob, this was a first for me - I have seen heads crack before and I was not too concerned about the face cracks , but when I first dunked it in the bath and saw the ports bubbling ( and that was live, not staged) I was amazed how they could have sold a £2600 engine in that condition - re manufactured my arse - £50 long engine with £100 worth of cheap bits and a bit of paint
@@BritannicaRestorations For those cracks to have formed inside the head like they did it must have been caused by freezing, while still bolted down on the engine, which was probably left outside on the scrap pile over winter. I'm still learning thanks to you Mike. better luck for this year... Rob.
I had a very similar problem with my 300Tdi head. The 90 used a little coolant and used to belch out steam for the first couple of miles in the morning, proper road filling fog.. but otherwise ran OK. Took it to my local LR specialist who had the head 'pressure tested'. Allegedly the head passed the pressure test, was skimmed and it was rebuilt with a new head gasket......No difference. As a test I used to park up on the night and release the pressure in the header tank. It would start the following morning with no steam. I ended up doing the job myself with a multi layer gasket (specialist had fitted a composite), new head bolts and a Turner gas flowed head. It has been utterly perfect since and, thanks to your brilliant advice and guidance, was a really enjoyable job to do. Cheers Mike. Happy New Year!
As I may have mentioned old heads are becoming consumables - costs more to properly refurbish them than get a new one!
Excellent demo Mike ;-)
Glad you liked it!
I fear this is exactly the problem with mine. It's down a bit on power, I gradually lose coolant and I can't find a leak anywhere, even used UV dye. The valve stem seals have gone anyway so I plan to buy a new built up head and just replace it, but if I can I'll keep and test the old head to try and see if it's cracked like this. Excellent work Mike.
Thanks - seen this before but not this bad!
wow ive never seen that!
Brilliantly caught...how good it is when explaining a problem...and one gets an excellent example...sad for the owner...but heyho check before you start...well done Mike
Glad you enjoyed it!
Brilliant love it keep up the great work
Thank you! Will do!
😮 That's another excellent 300 tdi engine video 👍 Thank you Mike 🙏🏻
And we are thankful for the extra mile 👍
Glad you liked it!
"Cracking head, Gromit..."
Blimey.
Lol!
That was quality 😎👍
Thanks
You couldn't find a better example of a dodgy head (and a dodgy supplier) if you tried!
I'd say this was a set-up except that you can see Mike is as surprised as everybody else. :-D
Yeap it was realtime and I have never seen one as bad!
My 1998/9 300 head I have found I have got 5 visible cracks so far. It was down on power. Not using any water or oil at all. Something was nagging me that something was not right. Eventually ripped head off. Nothing obvious at first until I cleaned it up. Cracks behind 3 of the glow plugs and between injector and inlet port on 1&3.
I have seen them crack the injector ports and use bucketfuls of water!
Yes as have I. I had a 1997 disco commercial that towed a big trailer daily and it chewed through several heads the last one was so bad you couldn’t keep water in the bloody thing. This has been different though. Apart from lots of seals I didn’t touch the lump when I rebuilt it as it was running great. After two years of restore/rebuild it just has not been very powerful. I put it back on the road in October and not once towing has it even got hot or used water. Fuel economy on the floor and oil still clean from service but not used a drop of water or oil. The coolant is a vile colour though hence it started me thinking about heads etc.
Brilliant 👍
Thanks to your vid I just found exactly the same elusive failure - on a ported head which wasn't run dry or frozen. It failed during an uphill tow.
Based on your accent I thought you must be fairly local (Lancashire) - then I checked your site... couldn't be more wrong! 🤣
Keep up the good work 👍
Glad it helped
Brilliant practical example. Just feel for the poor bloke that purchased it thinking it was a goodun.
Totally agree with you Mike: BRILLIANT!
Thanks!
Surely there’s got to be some legal recourse for whomever paid 2600 for this
Thank you for pointing out some of the 300Tdi cooling issues clearly. I’ve been saying for years that even in perfect working order they are marginal (especially here in Australia) . And very interesting to see some support for the idea the 200 Tdi was better (in a lot of ways)
Glad to help
When you stop learning, Their screwing the lid on, Have a Good 21 Mike.
Thanks Antony!
I think frost damage, I've seen several cast heads with splits like that.... Happy New Year, take care...
Obviously not pressure tested then
@@BritannicaRestorations What a bloody joke, is his supposed to be a reman how could anyone supply this without pressure testing it after they carried the works out, maybe the company should be named, how many others leave in this state.
I would be bloody fuming if I bought that 🍋
AND for £2600!
I would have thought the core plugs in the head would have popped
@@BritannicaRestorations plus the cost to fit and later remove it 😡 can you imagine making a warranty claim once it had been fitted, sorry mister customer you must have caused the cracks when it was fitted.
If not resolved the unfortunate owner should be naming this company.
Cheers for the link back to this one. I have seen it before which is why my brain probably arrived at my current conclusion. I hope we are both wrong and it's something else. Need to get some stuff to test with now. I have the head off my original lump that im positive is ok. 200 heads are on the shelf with rocking horse shite and hens teeth! Can you fit a 300? Idea just popped in then
That ain’t a crack, it’s a chasm.
All the very Best to you for a better 2021, a super vid, so informative, making me more a 200tdi fan
Thanks, you too!
My bath sounds like that sometimes after a curry .
lol!
Now that was such a great film. Unreal. Tizer, brilliant. 😏
Thanks
Brilliant vid 👍 very impressive cracks!
Glad you enjoyed it
Bloody excellent vid mate 👍👍
Glad you enjoyed it
Very informative video Mike, ,thanks
Glad you enjoyed it!
05:58 now that I have a better understanding of how effective I might use the heater matrix, and perhaps even upgate it 🙄
The best matrix is the 300Tdi one as the hoses come out the right side towards the engine, not like a Td5 which points to the front
Although the matrix is better it is not an easy fit an older truck ( longer) better be good at sheet metal work!
@@BritannicaRestorations I got it. Thank you Mike 🙏🏻
Fiendish analysis of head injuries, Mike. Further cause demonstration experiment now due to conclusively prove the unequal block circulation theory : take a scrap block and apply a hosepipe at the water inlet . Best done outside and compare the resulting water fountain effects, which ought to be equal in all head transfer holes, but your theory should confirm prostate problems at the rear end (!). Instantaneous ice formations a bonus. Happy New Year ! Phil.
Yes but I think it would freeze before I got set up!
@@BritannicaRestorations One for the Arctic summer then!
Love your experiments Mike. Great content
Glad you like them!
Subscription renewed again. Glad you got rid of Patreon, I had quite a bit of trouble with that. All the best for 2021 Mike.
Yes my own system works quite well - I think a lot of us are moving to different platforms - I am now mirroring on Utreon - daft name, but less politics and better searching
Would that sort of damage show up doing a smoke test instead of compressed air? Happy New year by the way.
I do not think so as Smoke is only 1/2 Psi
Thats interesting. As its only blowing through the outlet valves, maybe the cracks were caused by too high egt´s?
Hard to say...
Do Jamesons make Tizer now? ....wow!!......almost as many bubbles in the drink as from that head :)
Maybe that's how they make it - or Irn Brew!
@@BritannicaRestorations 😂😂😂
what a spectacular faillure.
Happy new year Mike.
You have yourself a colander.
The rear core plug failed on my 300TDI, so engine out. The people doing the job asked me whether to fix the head or a replacement; I went for a new replacement. Okay, no name on it but after a few years since the job, it's still working.
When I pulled the valves on the old head, there was a like a sheet of carbon covering some inlet ports. I've never seen anything like it and no, silly me didn't take a picture. Some day I'll have it checked out.
Is there enough metal in the block to have additional water channels drilled, so the 2.8 head could be used?
Just had to replace a td5 cracked head!
Heads are becoming consumables now on older engines!
@@BritannicaRestorations I try not to think about it haha! learnt a lot from your vids keep it up!
Is that a pallet of racoon food in the back ?
Yeap - gets hungry over winter!
"Oh, 'tis nuthin' but a scratch"...
"Remanufactured head" supplied by Liar & deShonk Pty Ltd...
Definitely due a celebratory Tizer er Jamesons. You'll be melting that one down then.
Looks like I need a bigger furnace!
Might that be frost damage those failures were radial cracks, cylinders normally fail longitudinally due to hoop stress? Wasn't at least one core plug changed on that engine it had silicon sealer on it, probably had problems sealing it as the hole was slightly out of shape. You wouldn't keep the coolant in that engine very long with those massive cracks, you would be lucky to get to the end of the road with those leaks. It's a pity you didn't have a flow meter on your test rig, you could calculate the leak rate.
Core plugs in the head didn't pop
@@BritannicaRestorations They might have done in the past.
hi mike, you know its kind of frustrating -You tell us/me, all the things i did wrong rebuilding my series machine 3 years before. Why you didnt show it earlier? jaja. And you what is the best - the machine is loosing coolant and i dont where ...
I am sorry Bernd - I will get Dr Who to post it earlier! lol!
I Think you should tell us where is came from so we can avoid it.
Whats the customer going to do ? Send the engine back ? "Get the book of excuses out" it was ok when it left here mate !!!
That is the normal excuse or warranty void as you opened it
Let’s fill it with water and put it outside and see it crack big time lol
I think it is for the furnace!
Hi Mike, great vid and very helpful information. I wonder, if you can improve the 300Tdi resp. 200TDi engines with external measures. Are there high-efficient classic waterpumps as one to one exchange part? Can I put an additional, electrical waterpump to the pipe/tube system, in order to fasten circulation speed? I think of pumps, for example, which come with Webasto or Eberspächer heaters? Or DEFA electrical powered pre-heaters (230V AC), which are very common on Scandinavian cars.
I was toying with the idea of and electric pump on the heater outlet to the rear of the head to the heater - that would suck water out of the head and maybe give better circulation - maybe a Webasto or Eberspächer would do - -I have seen the same system on Dodge mini vans here as the heaters were rubbish in the cold
@@BritannicaRestorations Good idea, perhaps worth to give it a try and stuff for one of the next vids😉😁
Check these pumps out

There seems to be a number of European vehicles with coolant pumps to aid circulation
All I need is a Tdi!
@@BritannicaRestorations Thanks for the link, Mike. I am going to check it.
Can you tell me where it came from please so I can avoid having the same problem.
Maybe later - this is ongoing
Hi Mike how thick is the rubber gasket thanks
8/10mm
Hi Mike thanks for the reply
So that was supposed to have been a tested head...? I think yiu should name and shame haha.
Do you rate those spanish/Chinese new heads then?
The engine was supposed to be 're-manufactured'
Spanish heads are good, Chinese ok. Watch out for the fully rebuilt cheap heads as they say they are made in the UK but are Chinese and the valves are fitted in the UK
@@BritannicaRestorations ah right okay, I am in an odd predicament at the moment myself where I'm contemplating taking the head off to look into an issue, but also thinking shall I just say to hell with it and get a new head ready rather than take the old one off and be without the old girl for a while while it goes off for a test and and Skim 🤔
Thanks for your videos BTW, they are a constant source of interest to me 👍🏻
These 25 year old heads have had a lot of heating and cooling over the years and cracks never get better.
By the time you pay for a pressure test, skim and then measure the valve heights ( normally with a Tdi what you take off the head you take off the valve seats) and machine the seats where needed it may work out the same as a bare head
@@BritannicaRestorations thank you for that 👌🏻 you Sir are a legend 👍🏻
